Bill Williams River National Wildlife Refuge

Bill Williams River National Wildlife Refuge is off SR 95 (between Mileposts 160 and 161) at the delta of the Bill Williams River at its confluence with Lake Havasu (the Colorado River). A 9-mile corridor along the river encompasses desert riparian and upland habitat. Named after a trapper who explored the area in the 1800s, the 6,000-acre refuge preserves the last remaining flood-regenerated riparian habitat in the Lower Colorado River Valley.

The refuge is home to beavers, bobcats, foxes, mule deer, bighorn sheep, raccoons and 355 species of birds.

Fishing and limited hunting are permitted (in season). Camping is prohibited. A high-clearance, four-wheel-drive vehicle is recommended.
